I find this all pretty interesting, so thanks for posting.
I voted 'other', as for me there was a weird mix of things I was nodding along to, and things I was screwing up my nose over. So I'd say I found it interesting, and with some good points, rather than being something I agree with. I'll try and break that down a little into some more transparent points.
1) I don't like atheism being discussed as an ideology. It's not. With some people, atheism is beginning to conflate with 'New Atheism', which I'm personally not a fan of. It's inaccurate at best. I wouldn't go so far as to stop calling myself an atheist, but I understand the author's point in that regard. Words and meanings move, and it's possible that the word atheist is beginning to represent a particular ideology, and to include elements of anti-theism is many minds.
2) Conversely, I find the "New Atheists' interesting. I liked the presentation style of Hitchins, and am learning to enjoy the diversity of Harris' perspective when compared to Hitchins and Dawkins. I think the author is making a mistake by treating the 'New Atheists' as a single idealogical blob when it's not. There is variance. However, my first point stands since I don't think it's only the author who does this. I think it is a common mistake.
3) The very influence and impact of the 'New Atheists' has spawned both followers and copycats. It's at once both completely understandable, and contributing to making my first point more impactful (unfortunately).
4) I have no issue with scientific approaches to things, and I think Harris is an example that scientism can at once approach areas that it traditionally hasn't (eg. morals) and not exclude areas it sometimes has (eg. mysticism). For me, though, the authors point about secularism being an important goal, and secularism not requiring atheism is absolutely correct, and a massively important point. Honestly, and in truth, I could care less if people believe in God, Gods, pantheism, atheism, or whatever. What I care about, truly, is secularism. A religious person can be either an ally or an opponent in that battle. An atheist could too, for that matter.
So, in brief summary, much of what the blog says is overstated. But I think the points made re: politics alone are massively important, not commonly discussed, and needs to be better addressed by any sort of 'atheist movement'.
What I have seen of atheist movements is that they tend to be based on scientism or ideology, and sometimes don't appear as politically aware as they could be.
